METHOD OF MAKING AND PROJECTING PICTURES.

Specification of Letters Patent.

Application filed. January 6, 1917. Serial No. 140,896.

To all whom it may concern:

Be it known that I, FREDERICK E. DAVIES, a citizen of the United Statesof America, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful improvements in Methodsof Making and Projecting Pictures, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a method of making and projecting pictures,and has special reference to the projection of pietures, sketches,illustrations or delineations on a screen as the same are drawn,painted, or otherwise made.

My invention, in its broadest aspect, involves means of producing on ascreen or other background, on a large scale, pictures as they are made,built up or otherwise produced, on a small scale, at a point remote fromthe screen or background. This may be accomplished by using astereopticon or suitable projecting machlne, and interposing a mediumupon which pictures, either negative or positive, may be produced. Thein- .terposed medium may be in the form of a perforated, transparent ortranslucent base and on this base is drawn, painted, or otherwiseproduced a picture, by using a suitable instrument and opaque ortranslucent substances, applied to or one on the other, so that theprojected picture will have for its outline and details those portionsofthe base and substances thereon which light has penetrated. By usingvarious kinds of bases and substances it is possible to project variouskinds of pictures on to a screen, for instance, pictures that arecolored or pictures in has relief.

Since my method involves the use of projecting machines, reference willnow be had to the drawings, wherein Figure l is a longitudinal sectionalview.

of a suitable projecting machine;

Fig. 2 is a plan of the same;

Fig. 3 is an elevation of a base or work plate prepared for theproduction of a picture and illustrating the manner of producing thesame,

Fig. 4 is an elevation of another base or work plate showing anothermethod'of producing a picture, and

Fig. 5 is an elevation of another base or work plate showing anothermethod of producing a picture.

The machine or apparatus which I have used for projecting rays of light,upon a screen comprises a suitable source of light, as a lamp 1, whichmay be adjusted relative to a lens 2 and in order that the lamp may besafely used in a theater, auditorium or structure under fireregulations, the lamp is inclosed by a fire proof housing 3. Associatedwith the lens 2 is a mirror or reflector 4t and another lens 5. Themirror or reflector 4 is adapted to reflect light rays from the lamp 1,to a base or work plate 6 in proximity to the lens 5 and as the rays oflight penetrate the base or work plate, the light rays pass through anadjustable lens 7 to an adjustable mirror or reflector 8 and areprojected on to a suitable screen or background (not shown).

The method involved with the projecting machine or apparatus residesprincipally in the preparation of the base or work plate 6 by which apicture is produced, and reference will first be had to the method whichincludes the base or work plate shown in Fig. 3. This base or work platecan be made of an opaque piece of material 9 provided with closelyarranged perforations or apertures 10 and when the base or work plate isplaced in the position shown in Fig. 1, the light rays will pass throughthe perforations or apertures 10 and thereby pro- Patented Apr. 9, 1918.v

duce a spotted effect on the screen or background. Now, by'using opaquematter 11 or a translucent substance of any color, the perforations orapertures 10 may be closed, covered or blotted out, so as to completelyexclude light, as is the case with opaque matter, or allow light topenetrate or pass through the perforations or apertures, according tothe nature of the translucent substance. In placing the opaque ortranslucent matter on the base or work plate, a picture can be outlinedor produced, and as an example, there is shown a Maltese cross which isformed by filling or blotting out the perforations and allowing othersto remain open so that light rays will pass through and be projected onto the screen. It is also possible in connection with this kind of baseor work holder to perforate the same so that a spotted configurationwill be shown on the screen and after the spotted configuration has beenobserved, the, artist into another configuration or picture. With theperforations or apertures very small a stippled effect will be producedon the screen, and it is a well known fact that stippled pictures are asdiscernible or as readily understood as line pictures, and furthermore,that a stippled picture can be more readily transformed into anotherpicture, by combining or blotting out certain stipples than what can beaccomplished by a line picture.

Another method by which very satisfactory results can be obtained isthat of using a transparent base or work plate 12, as shown in Fig. 4,and placing thereon or applying to the face of the plate translucentsubstances or matter, either in liquid or pliable form. Assuming that apiece of glass or a piece of celluloid is used as a base or work plate,it is an extremely easy operation to apply thereto, by'pen, brush orsuitable instrument, translucent liquid, as water coloring or a thinpaint, or translucent matter in the form of paste or jelly that may bemolded and shaped upon the base to provide portions of greater densitythan others. By varying the density of the base or transparent workplate, shadows of varying density Will appear on the screen, and in thismanner realisticpictures having high lights and a wealth of detail mayappear as the artist produces the same upon the base or Work plate. Byplacing translucent substances, one upon the other, somewhat in the formof coatings, the passage of light rays through the base or work platecan be regulated'to a nicety and with sharp and well defined shadowsupon the screen a picture will stand out in bas relief. The base or workplate shown in Fig. 4 has a translucent substance applied thereto so asto decrease the transparency of the base or work plate, and with theartist or operator using skill in the application of the substances aslowly growing picture will be outlined and produced upon the screen,with the. same degree of interest to an audience as though the actualoperations of the artist were observed, at the base or work plate.

Still another method is involved and by reference to Fig. 5, it will benoted than pictures, sketches, illustrations or delineations may beproduced upon a screen by perforating or aperturing a base or workplate. As an instance of this method, an opaque base or. work plate 13is placed in position and then by perforating or aperturing the base 'orwork plate, as at 1 k and 15, a composite design or picture is madewhich is observed upon the screen by reason of light rays passingthrough the perforations or apertures. To facilitate perforating thebase or work plate 13, the picture to be rcproduced may be previouslydrawn or sketched thereon to guide the operator in perforatlng the workplate. For instance, t e perforato certain perforations, so that the onedesign is wiped out on the screen, leaving the other design. An operatormay start in and indiscriminately perforate the base or Work plate andthen close certain of the perforations so that the-remainingperforations will produce a picture on the screen. This method permitsof a highly or complex stippled picture being first produced togradually fade away into one or more other pictures, and in this method,as well as those previously described, itis apparent that the picturesas produced upon a screen may be photographed by a moving pictureapparatus, and by speeding up the film or eliminating certain sectionsor scenes thereof, a picture may be rapidly reproduced by a movingpicture apparatus.

\Vhat I claim is 1. A method of projecting pictures, consisting insketching a picture on a perforated medium with a light excludingsubstance by means of an instrument which can be so manipulated as toproduce either pen or brush effect, and thereby closing some of theperforations of said medium, allowing a llght to shine upon said mediumand holding the instrument in such a osition as to allow the light topass freely t rough the other perforations of said medium on to ascreen, whereby as the light excluding substance is applied a slowlygrowing picture appears on the screen.

2. A method of projecting pictures consisting in allowing a light toshine on a medium, perforating the medium and applying a light excludingmedium to the perforated medium, by an instrument which can be somanipulated as to produce a slowly growing picture having for itsbackground and characteristic features the shadows of the lightexcluding medium.

3. A method of producing screen pictures, consisting in allowing a lightto shine on the perforated medium and then placing opaque matter on theperforated medium to produce a slowly rowing picture having for itscharacteristic features the shadows of the opaque matter.

4. A method of simultaneously making and projecting pictures consistingin allowing a light to shine on a medium capable of having the lightpass therethrough, and then placing matters of greater density on saidmedium to produce a slowly growing picture having shadow portionsvarying in density.

5. A method of producing pictures consisting of allowing a light toshine on a asee ieo g medium capable of having light pass therelight toshine on said substances to produce 10 through and applying substancesvarying in a 'slowly growing picture on the screen as densities to saidmedium to produce screen the substances are sub3ected to light shadowsof varying densities.
